Abstract

Abstract: A simplified multiple DOFs lumped-parameter elements model is established to study the dynamic properties of vibration path in powertrain-vehicle’s system in high frequency range. The relationships among isolator, interface velocity and each component’s mobility are derived. The main parameters influencing the dynamic properties of the vibration paths are determined by component’s parameter study. Finally, effective methods are proposed to perform dynamic design of the powertrain-body vibration transfer system.

Key words: vibration and wave, powertrain, mechanical mobility, vibration transfer, dynamic design
